SHqigao HSY-7000B Automated Disintegration Tester (Integrated, Motorized Rack Inversion)

Overview

The SHqigao HSY-7000B Automated Disintegration Tester is an integrated, electromechanical pharmaceutical testing instrument engineered to evaluate the disintegration behavior of solid dosage forms—including suppositories, vaginal tablets, and effervescent tablets—under standardized aqueous conditions. It operates in strict compliance with the Chinese Pharmacopoeia (ChP) Volume IV, General Chapter 0921 “Disintegration Time Limit Test”, as well as aligned methodologies referenced in USP General Chapter <701> and EP 2.9.1. The system employs a precisely regulated water bath environment coupled with programmable, motor-driven inversion of stainless steel mesh racks to simulate physiological mechanical agitation. Its core measurement principle relies on visual endpoint detection: the time at which no palpable residue remains on the mesh disc (excluding insoluble coatings or capsule shells), confirming complete disintegration. This endpoint is determined either manually by operator observation or via optional integrated camera-based monitoring (not included in base configuration).

Key Features

• Triple-bath architecture: Three independent 5 L water bath vessels operate simultaneously, each equipped with its own temperature sensor, magnetic circulation pump, and motorized rack-inversion mechanism—enabling true parallel testing of three samples under identical thermal and mechanical conditions.
• Motorized rack inversion with dual-mode operation: Each stainless steel mesh rack (Ø50 mm, 9 × 4 mm apertures) is driven by a precision stepper motor for repeatable 180° inversion cycles; manual override is available for calibration verification or emergency intervention without power interruption.
• High-stability thermal management: Patented magnetic-drive circulation pumps ensure uniform heat distribution across the entire bath volume, minimizing axial and radial thermal gradients (<±0.15 °C within 5 cm radius from center), critical for reproducible disintegration kinetics.
• Intuitive dual-display interface: Separate LED segments simultaneously show user-defined setpoints (temperature, duration, inversion interval) and real-time process values—enabling immediate deviation detection during GLP-compliant execution.
• Preset operational profiles: Three factory-configured shortcuts (P1: 30 min / 10-min inversion; P2: 60 min / 10-min inversion; P3: 30 min / no inversion) reduce setup time and minimize parameter-entry errors in routine QC workflows.
• Comprehensive safety and diagnostics: Built-in fault detection triggers audible/visual alerts for temperature overshoot (>±0.8 °C), timing drift (>±1.0 min), pump stall, or rack motor stall—log entries are timestamped and retained in non-volatile memory for audit review.

Sample Compatibility & Compliance

The HSY-7000B accommodates standard pharmacopoeial sample holders: cylindrical transparent tubes (60 mm × 52 mm ID) paired with two perforated stainless steel discs per test position. It supports all ChP-, USP-, and EP-specified dosage forms requiring disintegration assessment—including lipid-based suppositories, hydrophilic vaginal tablets, and compressed effervescent tablets. All wetted components—including mesh discs, tube retainers, and bath vessel liners—are fabricated from AISI 316L stainless steel, certified to ASTM A240 and compliant with ISO 10993-1 for short-term contact with pharmaceutical preparations. The instrument meets electromagnetic compatibility requirements per IEC 61326-1 (industrial environment) and electrical safety per IEC 61010-1. Full traceability documentation—including factory calibration certificates for temperature and timer modules—is provided with each unit.

Software & Data Management

The embedded control firmware supports audit-ready data integrity per FDA 21 CFR Part 11 requirements when used with optional PC connectivity (RS-232 or USB-to-serial adapter). Logged parameters include start/stop timestamps, actual vs. setpoint temperature curves (sampled every 10 s), inversion event timestamps, and fault codes. Exportable CSV files contain full session records with unique test IDs, operator login tags (via optional password-protected user accounts), and digital signatures for electronic record validation. No proprietary software installation is required—raw logs are readable in Excel or validated LIMS environments.

Applications

• QC release testing of suppositories and vaginal tablets against ChP/USP disintegration limits (e.g., ≤30 min for lipid-based suppositories at 36–37 °C).
• Stability-indicating method development for modified-release formulations where disintegration onset correlates with dissolution profile shifts.
• Comparative evaluation of formulation variables (e.g., surfactant type, melting point modifiers) on melt-dispersion kinetics.
• Process validation support for semi-solid manufacturing lines, including correlation studies between disintegration time and rheological properties of base matrices.
• Educational use in pharmaceutical sciences laboratories for hands-on training in pharmacopoeial testing principles and GLP documentation practices.

FAQ

Does the HSY-7000B comply with USP <701> requirements for disintegration testing?

Yes—the mechanical design, temperature control stability (±0.3 °C), timing accuracy (±0.5 min), and rack geometry fully satisfy USP <701> specifications for both basket-rack and disk-assisted configurations.
Can the instrument be integrated into a networked laboratory information management system (LIMS)?

Yes—via ASCII protocol over RS-232, it transmits structured test logs compatible with common LIMS ingestion modules; validation protocols for LIMS interface are available upon request.
Is calibration certification included with shipment?

Yes—NIST-traceable calibration certificates for the PT100 temperature sensors and quartz-crystal timer module are supplied, along with as-found/as-left data for initial qualification.
What maintenance is required to sustain regulatory compliance?

Annual verification of temperature uniformity (per ASTM E2251), timer accuracy, and inversion cycle repeatability is recommended; SHqigao provides certified service engineers and IQ/OQ documentation templates.
Are replacement mesh discs and transparent tubes available as consumables?

Yes—genuine SHqigao spare parts (P/N: HSY-MESH-316L-50 and HSY-TUBE-ACRYLIC-60×52) are stocked globally and supplied with material certifications.
